It is a fact that the Animation and architecture have common and strong bonds in various forms. According to animators, and architects as well, there are two main and vital concepts which are the basics of animation, they are Timing and Spacing. The paper represents an analogy between animation and architecture focusing on these two concepts. So, in the following sections we discover the relation between animation and deforming geometry in architecture. By looking through the history and theory of architecture we find many architects' attempts to apply animation as a concept within their forms. This paper will review what pioneers have achieved in designing through animation. At the end of the paper a case study is being analyzed by showing how the concept of animation is applied to an existing building due to the research's main points.
